I armQS by the pawl 6, and then the disk moves with said. arm 3;consequently the movement is resisted by the friction of the' sides orfriction-plates 15 of the-'disk against the cheek members of thebifurcated lever or arm 2, thereby resisting or 'absorbin the shock, dueto the rebounding of the spring C,in a veryeiicient manner. Inthe actionthe disk 5 rotates in one direction only, it being controlledalternately by the -arm 2, and then by the pawl and arm 3.

Hence the wear on all Africtional parts will beuniform, and the actionsmooth and eiicient.

This mechanism is comparatively simple' and inexpensive, and can readilybe attached to .automobiles or other vehiclesnow in use, or to newmachines, at small cost and-with satisfactory results. Y

1. In a shock absorber, in combination as described, with a' pair ofhingingly con nected arms or levers, one of said levers being dualorbifurcated and having opposite frictional lcheek portions,- anaxis-pivot therethrough, a rotatable friction disk mounted on saidaxis-pivot and laterally embraced between the frictional cheek portions-of said bifurcated lever, the .other lever having a cylindrical headthat surrounds, fits and incloses the periphery of said friction disk,said lever carrying a swinging pawl hingingly seated within a socketrecess in the lever arl'n, and said pawl being provided with a hingedhead vmember and ,ada ted to act against the peripheral face e disk byknuckle joint action for engagement therewith in one direction ofmovement, and'means including the oppositely pressing cheek-springs forregulating the resistance tension against the sides of the disk.

counter matching said cheek members, a-

pivot or axis-bolt therethrough, a second arm having its headsurrounding said disk and approximately fitting the space between saidcheek members, a hinged pawl carried by said second arm and engaging theperipheryf of the disk for rotating it in one direction, said pawl havina hinged engaging end for contact with t e face of the disk, a springsupported on the-axis-bolt for pressing the cheek-member toward thedisk, and contact-plates of frictional material between" the adjacentfaces of the disk andicheek members, the outer ends of said arms adaptedfor pivotally attaching means.
